Key Parameters

Substitute Part Grouping Explanation

Substitution of the AH180N-WG-7 is determined by the following critical parameters:

Functional Requirements:

• Omnipolar switch function (detection of both north and south magnetic poles)
• Hall Effect technology
• Surface mount packaging compatibility (TO-236-3, SC-59, SOT-23-3)

Electrical Compatibility:

• Supply voltage range must encompass or overlap with 2.5V ~ 5.5V
• Operating temperature range must cover -40°C ~ 85°C
• Output type and current ratings must be compatible with circuit design

Sensing Performance:

• Sensing range parameters (trip and release thresholds) determine application suitability
• Output type (open drain vs. push-pull) affects circuit integration requirements

The substitute parts listed below meet the functional and packaging requirements while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Open Drain Output Replacement: The TLE4913HTSA1 (Infineon Technologies) provides the closest functional match with open drain output topology identical to the AH180N-WG-7. This part maintains the same sensing range parameters (±5mT trip, ±4.2mT release) and operating temperature range. The TLE4913HTSA1 carries active product status, AEC-Q100 automotive qualification, and temperature compensation features. Supply current is higher at 2.5mA compared to 16µA, requiring circuit evaluation for power-sensitive applications.

For Push-Pull Output Applications: The SL353 series (Honeywell) offers two packaging variants: SL353HT (Tape & Reel) and SL353LT (Cut Tape & Digi-Reel). Both provide push-pull output with 5mA maximum output current and wider sensing range (±11mT trip, ±9.5mT release). The SL353LT variant demonstrates superior supply current efficiency at 3µA, making it suitable for battery-powered or low-power applications. Both variants maintain active product status and full RoHS compliance.

Compliance Considerations: All substitute parts maintain ROHS3 or RoHS compliance and operate within the -40°C ~ 85°C temperature range. The TLE4913HTSA1 includes AEC-Q100 automotive qualification for applications requiring automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can the SL353HT or SL353LT replace the AH180N-WG-7 directly? A: Functional substitution is possible with circuit modifications. Both SL353 variants provide omnipolar Hall Effect switching in compatible packaging. The primary difference is output type: SL353 series uses push-pull output versus the open drain output of AH180N-WG-7. Circuit pull-up resistor configurations must be adjusted accordingly. The wider sensing range (±11mT vs. ±5mT) may affect application sensitivity thresholds.

Q: What is the key difference between SL353HT and SL353LT? A: Both parts are functionally identical with the same electrical specifications and sensing parameters. The difference is packaging format: SL353HT is supplied in Tape & Reel (TR) format, while SL353LT is supplied in Cut Tape (CT) & Digi-Reel format. Selection depends on procurement and assembly requirements.

Q: Is the TLE4913HTSA1 suitable for automotive applications? A: Yes. The TLE4913HTSA1 carries AEC-Q100 automotive qualification and includes temperature compensation features. It maintains open drain output compatibility with the AH180N-WG-7 and operates within the same temperature range.

Q: How do sensing range differences affect substitution? A: The AH180N-WG-7 has a ±5mT trip threshold, while SL353 variants have ±11mT trip threshold. Applications requiring detection of weaker magnetic fields may not function with SL353 substitutes. The TLE4913HTSA1 maintains the ±5mT trip threshold, making it more suitable for applications with tight magnetic field specifications.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts meet RoHS compliance requirements (RoHS Compliant or ROHS3 Compliant status).

Q: What supply current differences should be considered? A: The AH180N-WG-7 draws 16µA maximum supply current. The SL353LT offers the lowest consumption at 3µA, making it optimal for battery-powered designs. The SL353HT draws 640µA, and the TLE4913HTSA1 draws 2.5mA. Power budget analysis is required for applications with strict current limitations.
